hey so I installed my JWT filter and OEM ztube with no problems (except the rubber on the heat shield was kinda a pain). Just for fun I was looking at the service manual and noticed there is an "O-ring" between the MAS and the air cleaner case that should be replaced after every disassembly. I have attached the diagram from the manual and the o-ring is item #13. My question is does anybody remember seeing this? I don't remember seeing any O-ring when I did the install and now I'm kinda worried sorta...

 

The o-ring is counter sunk in the maf housing. I installed the JWT popcharger and did not bother replacing the o-ring. You should be ok.

 

thanks for the quick reply - i just removed my filter and sure enough there it was ... hahha... don't know how i didn't notice it the first time around. thanks again.
